To read the full abstract: Nat Commun 2019;10:163.Central estrogen signaling via estrogen receptor alpha (ERα) coordinates energy expenditure, reproduction and, in concert with peripheral estrogen, impacts skeletal homeostasis. Here, the authors showed that eliminating ERα in kisspeptin arcuate nucleus neurons resulted in high bone mass phenotype in female mice only.<p clas...

Brief Summary: This study marks significant progress in understanding ancient genomes, particularly in deciphering chromosomal sex, aneuploidies, and their broader historical and societal implications. By extracting and analyzing DNA from ancient remains, researchers have uncovered new insights into disorders of sex development (DSDs) that were previously inaccessible. These authors pioneered a computational method to identify sex chromosomal aneuploidies. This approach indepe...
